I don't know what you are shooting or if you care about saving fur, but you could switch to soft points if you aren't already shooting them. They don't expand as violently as hollow points and ballistic tips. You will still have trauma in the immediate area of impact, but that is the case with a .22lr as well. The soft points will almost act as FMJ's on that small of a critter, and leave you a fair amount to eat, and of course always try for head shots when possible. They will still work well on coyotes as long as you are not worried about going through both sides, and they are cheaper. I don't have much experience with AR's, but have hear that some don't like to feed with softpoints, you might want to try a few before you buy bulk.
